Hot Water And Plant Growth: Effects Of Pouring Hot Water On Plants
As a general rule of thumb, most plants prefer water at room temperature. Some research, however, indicates that warmer – not boiling – water may have some beneficial effects on plant growth, even if those effects are minimal.
Around the garden, hot water can also be used to kill weeds and prevent disease. Consider each plant’s individual needs before experimenting with hot water, as it can cause serious damage to your garden if used improperly.
